Re: Serial admin console program

Clarify "config utility". minicom setup? Something else? Since you seem to be avoiding saying what your "device" actually is, and saying "device" over and over again is going to get confusing, I'm going to suppose your device is a "Gonkulator", or "Gonk" for short. Sounds like a serial parameter mismatch. If the baud, stop bits, data bits, and parity you configure in minicom (or whatever) do not match what the Gonk is using, then the serial port in your server will misinterpret the signals, resulting in funny characters (sometimes called "baud barf"). Possibly. Flow control provides a mechanism for one end to say "I'm getting overwhelmed -- temporarily stop sending". If the Gonk is not using either mechansim, then your terminal may very well work, at least at first. Software flow control works by sending special control characters (XOFF and XON), in-band with the other data. One side starts getting overwhelmed, and sends XOFF. The other side sees the XOFF and pauses transmission. The

Re: META: message encoding/MIME types

Ben Scott — 2008-10-06T22:57:30

The original sender may well have sent using quoted-printable or something else. Mailman automatically converts everything that isn't 7-bit clean to a BASE64 transfer encoding. This is apparently "by design". I haven't cared enough to find out why. When it comes to the mailing lists, I generally try to be a facilitator. I don't set policy, beyond those made in response to certain legal and technical realities outside of "our" control. So I enforce what people ask me to. If "the membership" want only certain mail encodings to permitted, I'm sure I can come up with something. The rest of this is my personal opinion... There's absolutely nothing keeping a text-based mail client from decoding BASE64 to yield unencoded text. Indeed, this is a fairly trivial function to add, either in the end-user mail program, or in some intermediate program (MTA, MDA, etc.). The MIME standards were formally published in 1996, and had been in development for a number of years p

META: message encoding/MIME types

2008-10-06T21:49:54

What do we think about standardizing the transfer encoding types used for messages sent to this list? /me squints expectantly at Ben... Encodings like quoted printable are more or less readable in text-only mail clients. But lately this list has been seeing things like the above message... in base64 encoded text/HTML. What do you all think? Maybe I'm the only one using a text-based mail client. These days, it wouldn't surprise me. On the other hand, maybe someone on this list knows some tips I could use to learn how to decode base64 in my head. :D

In Minicom, flow control is under "Serial port setup", under "Configuration". (ALT-O in the program, or "minicom -s" from the command prompt.)

I saw something similar (symptom-wise) with a serial console server and it wound up that I had to turn off hardware flow control in agetty. I suspect it's a bad cable as five other machines work fine, but it's hundreds of miles away, and works with hardware flow control turned off, so there it is. In agetty, I removed: -h Enable hardware (RTS/CTS) flow control. It is left up to the application to disable software (XON/XOFF) flow protocol where appropriate. so, maybe something like: stty -F /dev/ttyS0 -crtscts would help? Somebody who has actually tried this before might help on syntax. -Bill ----- Bill McGonigle, Owner Work: 603.448.4440 BFC Computing, LLC Home: 603.448.1668 bill-6ft+4TUC7y9qCwUM1VThig< at >public.gmane.orgCell: 603.252.2606 http://www.bfccomputing.com/ Page: 603.442.1833 Blog: http://blog.bfccomputing.com/ VCard: http://bfccomputing.com/vcard/bill.vcf

Re: ethtool/nic question

Michael ODonnell — 2008-10-06T18:09:30

I'll second that, and I'll add that the Intel e1000 series of NICs (and the associated Linux drivers) generally work just fine and you'd be doing yourself a disservice by engaging in a FUD-induced leap from "narrowly constrained problems with a small set of integrated NICs on a small set of motherboards" to "IntelEnet==BAD!"

Re: ethtool/nic question

Darrell Michaud — 2008-10-06T17:45:09

I'm sure there's other advice out there but I'll throw in: Don't change the linux broadcom or intel gig-E ethernet drivers from their defaults without a specifically documented reason. They will autonegotiate to 1000 when possible under normal circumstances. Check your wiring, your switch, your switch's configuration first. My personal experience is that GigE automatically dumbing down from 1000 to 100 has not been due to an configuration issue in the linux drivers. bruce.labitt-TPoik56scW1BDgjK7y7TUQ< at >public.gmane.org wrote:

In other words, lots of truly "floss" podcasts also come in an ogg flavor, because of mp3 being patent-encumbered and whatnot.

Re: portable music players

Travis Roy — 2008-10-06T13:08:54

Why do you say that's strange? Out of the 20 or so podcasts I listen to, only one is not sent in mp3 format, and that's sent in some apple format so that you get chapter ticks on your iPod when listening to it (it also changes the "coverart" for each section). That podcast (Quackcast) does offer MP3, but you have to go manually download it. Fact is, for better or worse, mp3s can be played by basically anything. If you want the widest audience the default is going to be mp3.

Yes, I hope to buy a player on their supported list. Coincidentally, Paul Louden of Rockbox is interviewed on this week's FLOSS podcast on twit.tv. That might provide a bit of additional background, perhaps a little push to get you or others to try it: http://twit.tv/floss43 Strangely, their podcast is only available in MP3 format...

Re: Serial admin console program

Serial is tough in comparison to other technologies because it has so many different parameters (baud rate, parity, stop bits, IO port, IRQ, flow control, DTE/DCE, any I'm missing?) Assuming this in on a PCI-based PC (I have to admit I haven't read the entire thread), you might try "cat /proc/interrupts" while mc has the port open. This will show you if anything else is trying to share the interrupt with the serial port. Personal experience has shown me that serial ports sometimes don't like to share. :) See also /proc/ioports and /sbin/setserial.

Re: Serial admin console program

Ben Scott — 2008-10-06T01:08:56

Probably, but I doubt that's going to help you. You've rebooted both devices, which most assuredly clears any buffers associated with the serial ports. I'm going to guess that there's something different between the config that was working and the config you're using now. The most likely suspects are the serial port parameters. Double check your baud rate, data bits, stop bits, parity, and flow control. In particular, if one end is expecting flow control and the other end is not configured to provide it, things will sit there forever not flowing. You might also want to have your on-site people check for a loose cable. Maybe something got bumped while they were power cycling things.
